2.3 Dimensions and Weight
The AK-47 measures 870 mm in length with the stock extended and 645 mm without the stock; It weighs approximately 4.3 kg with a loaded magazine and 3.8 kg without. The AKM variant is slightly lighter due to stamped steel construction. The rifle’s dimensions and weight contribute to its portability and balance, making it manageable in various combat environments. The sturdy materials, including milled steel, ensure durability while keeping the weight moderate. These physical characteristics have made the AK-47 a practical choice for soldiers and users worldwide, balancing ease of carry with reliable performance in harsh conditions.
2.4 Magazine Capacity and Types
The AK-47 typically uses a 30-round curved box magazine, though larger capacities like 40-round or 75-round magazines are available. Magazines are made of steel, plastic, or polymer, with steel being the most durable. The standard magazine weighs around 0.43 kg when empty, while plastic magazines are lighter at 0.25 kg. Some variants, like the AKM, may have slightly different magazine weights due to design changes. The rifle also supports drum magazines for extended firepower. The magazine design allows for quick and easy replacement, enhancing the AK-47’s combat efficiency. Over time, various manufacturers have produced magazines with different materials and capacities, expanding the rifle’s versatility.
Design and Operating Mechanism
The AK-47 features a gas-operated, piston-driven system with a rotating bolt. Its durable design includes a forged steel receiver and a chrome-lined barrel for longevity.
3.1 Gas-Operated System and Piston Design
The AK-47 operates using a gas-operated, piston-driven system, which ensures reliable functioning in harsh environments. The gas piston, located above the barrel, is driven rearward by expanding gases. This motion cycles the action, ejecting the spent cartridge and chambering a new round. The system is simple, with fewer moving parts compared to other rifles, enhancing durability. The piston’s design allows it to function effectively even when exposed to dirt or debris, making the AK-47 highly reliable. This mechanism, combined with a rotating bolt, ensures consistent operation and contributes to the rifle’s legendary reputation for dependability in combat scenarios.
3.2 Trigger and Safety Mechanism
The AK-47 features a robust trigger and safety mechanism designed for simplicity and reliability. The safety selector is located on the right side, allowing the user to switch between safe, semi-automatic, and fully automatic modes. The trigger mechanism is straightforward, with a consistent pull weight that ensures predictable operation. The safety lever doubles as a fire selector, making it easy to operate even with gloves. This design ensures the rifle can function reliably in various combat scenarios, maintaining its reputation for durability and ease of use. The mechanism’s simplicity contributes to the AK-47’s legendary reliability, making it a preferred choice for military and civilian use worldwide.
Performance Characteristics
The AK-47 delivers a muzzle velocity of 715 m/s and muzzle energy of 2,010 joules. Its effective range is 300-400 meters, with a rate of fire of 600 rounds per minute.
